Look at ZServer/INSTALL.txt and ZServer/README.txt

Also try the ZServer start script:

  $ python1.5.2 z2.py -h

w_pcgi.py will compile the PCGI wrapper which you will need unless you are
using mod_pcgi or already have it compiled.

The basic idea of using PCGI and ZServer is this:

browser <--HTTP--> webserver <--CGI--> pcgi wrapper <--PCGI--> ZServer

Basically using PCGI with ZServer is exactly like using PCGI normally,
except for the fact that the long running process that the PCGI wrapper
communicates with is ZServer, not pcgi_publisher.py The upshot of this
difference is that you need to start ZServer before you can use PCGI, since
the PCGI wrapper does not currently know how to activate ZServer. Also you
need to configure ZServer to communicate w/ PCGI, which is normally done by
passing the path to a PCGI info file to the PCGI Server.

Clearly we need to improve our documentation, and our installation programs
:-( Note: we haven't yet overhauled the install documentation for Zope 2.
As always, we're open to constructive criticism, suggestions, and
contributions.
